🎯 The business: in a small plant, the right way to run a machine often lives in one veteran’s head. You film that person doing the task, let AI turn the video and transcript into a step-by-step work instruction with photos, then test it on the floor with an operator and get it signed off by the plant’s quality and safety leads. Shops pay you for documents that pass a customer audit and help train new hires, without buying a software platform.

Is this for you?
It suits someone who has worked in a plant, a machine shop or a quality department, or an engineering student who is comfortable in steel-toe boots. You need to be at ease asking a machinist with 30 years on the job to slow down and show you again.
It is a poor fit if you want desk-only work or dislike noise, early starts and safety gear. It is also wrong for anyone tempted to write a safety procedure from a video alone: lockout and machine-guarding steps must be checked on the actual machine by the plant’s own people.
Who pays, and what
Manufacturers and machine shops with roughly 10 to 200 employees, especially those chasing ISO 9001 or AS9100 certification, preparing for a big customer’s supplier audit, or losing experienced people to retirement. The buyer is the quality manager, the plant manager or the owner.
The timing helps. ISO 9001:2026 was published on September 16, 2026, and certification bodies describe a transition of about three years, with 2015 certificates staying valid in the meantime. Every certified shop will review its documents against the new edition. The standard requires "documented information" to be controlled: reviewed and approved, kept current, available where the work is done and protected from accidental change. Shops that wrote their procedures years ago, or never wrote them down, need help.
What they pay, as estimates from the research: about $150 to $500 per SOP, or a $3,000 to $10,000 project for a set of instructions or a quality manual. Software such as Dozuki, SwipeGuide, Tulip and GembaDocs exists, and larger plants use it. Many small shops do not want a platform to learn; they want someone to show up with a phone and leave with finished documents.
What it takes to start
| LLC and city or county license | $150 to $500 |
| One paid AI account on a business-grade plan (Claude Pro is $20 a month) | About $240 a year |
| Phone gimbal or tripod and a clip-on microphone | $50 to $200 |
| Your own safety gear: steel-toe boots, glasses, hearing protection | $100 to $250 |
| General liability and errors and omissions insurance (an estimate; plants will ask) | $300 to $1,000 first payment |
| Simple website, domain, business email | $50 to $150 |
| All-in | ≈ $890 to $2,340 |
Start to finish: the steps
1. Learn what a good work instruction looks like. One task per document, numbered steps that start with a verb, a photo for each step that matters, the tools and gauges needed, the quality checks and the safety warnings exactly where they apply. Read the documented-information requirements in ISO 9001 and how your target customers’ audits treat them.
2. Learn the safety rules you must not get wrong. OSHA’s lockout/tagout standard (29 CFR 1910.147) requires written energy-control procedures for machines, periodic inspections at least once a year by an authorized employee, and written certification by the employer. You can format and photograph a lockout procedure; the plant’s safety lead must verify every step on the machine and sign it. Never write one from video alone.
3. Make the business legal and insured. Plants will ask for a certificate of insurance before you walk the floor, and often for a signed confidentiality agreement. See Choosing a legal structure.
4. Set your data rules before you film. Customer drawings and processes are confidential. If the shop does defense or aerospace work, some drawings may be export-controlled, and they must not go into an AI tool without the shop’s export-compliance approval. Use a business AI plan whose terms exclude training on your inputs, and keep footage on the client’s systems when they ask. More in Contracts, client data and AI rules.
5. Make a sample on your own time. Film yourself doing a real task, such as changing a saw blade or calibrating a scale, and produce a two-page instruction with photos. It shows a plant manager in thirty seconds what they will get.
6. Sell a three-SOP pilot. Ask the quality manager which three tasks cause the most scrap, rework or training time. Film the best operator doing each one, with the operator’s permission and the supervisor present.
7. Draft with AI, then edit hard. Give the AI the transcript and your notes and ask for numbered steps in the plant’s template. Then check every number, torque value, setting and part name against what you saw. AI invents plausible specifications; you remove them.
8. Test on the floor and get it signed. A different operator follows the draft while you watch and note where they hesitate. Fix it, then have the quality lead approve it, and the safety lead approve anything that touches energy control, guarding or chemicals. The plant releases it in its own document system.
9. Translate with a human check. Many plants need instructions in Spanish or another language. OSHA expects training in a language and vocabulary workers understand, so a fluent person on the floor must review every translated step.
10. Grow into the larger jobs. After the pilot, offer a set of 20 to 40 instructions, a quality manual update for ISO 9001:2026, or help writing up corrective actions after an audit finding. Keep the per-SOP price visible so the plant can budget.
Pricing
| Three-SOP pilot | $600 to $1,200 |
| One work instruction, typical task | $150 to $500 |
| Set of 20 to 40 instructions | $3,000 to $10,000 |
| Quality manual update or corrective-action write-up | $500 to $2,500 |
| Translation with floor review, per SOP | $75 to $200 |
These are example prices; the per-SOP and project ranges match the research estimates. Complex setups, multi-machine processes and anything with long safety sections sit at the top. Price per document rather than per hour, so the plant knows the cost before you start.
The math
Take a busy month a year in: twelve SOPs at an average of $300 is $3,600, plus one corrective-action and manual job at $800, $4,400 in all. Costs are about $120 for mileage, $100 set aside for insurance, $40 for software and $20 for AI, $280 in all. That leaves about $4,120 a month before tax. Each SOP takes about five hours including floor time and edits (60 hours), the larger job about 10, and sales about 10, roughly 80 hours or about 19 a week.
Set aside a quarter to a third of profit for income and self-employment tax. See Small business taxes.
Getting customers
Start with plants where you or someone you know has worked. A former supervisor who knows you show up on time and respect the floor is worth fifty cold emails. Next, your state’s Manufacturing Extension Partnership center: its advisers visit small plants constantly and sometimes need someone to do the writing their projects call for.
A plan for the first ten: list 40 manufacturers within 45 minutes from your state manufacturers’ association directory or the chamber’s industry list. Send 40 short letters or emails to the quality or plant manager by name, with your two-page sample. Call each one a week later; aim for 10 plant visits. At each visit, ask which three tasks cause the most rework and offer the three-SOP pilot. As an example, expect 3 to 5 pilots and 2 to 4 repeat clients from that round.
Hello Mr. Kowalski, I write work instructions for small plants. I film your best operator doing a task, turn it into a step-by-step instruction with photos in your template, have another operator test it at the machine, and hand it to your quality lead for sign-off. It helps with training new hires and with document control as shops move to ISO 9001:2026. I have attached a two-page sample. Could I visit for 30 minutes and price three instructions for the tasks that cause you the most rework? Priya Shah, 555-0131
Channels, best to worst for small manufacturers:
1. People you know in plants. Former employers, coworkers and family; the trust carries.
2. Referral partners. MEP center advisers, independent quality consultants who would rather not do the writing, industrial distributors and machine dealers.
3. Manufacturers’ associations. State and regional associations and chamber manufacturing councils run plant tours and meetings.
4. Local ASQ section meetings. Quality managers attend, and a short talk on video-based instructions fits their programs.
5. LinkedIn. Search by title and county for quality and plant managers; post short before-and-after examples with client permission.
6. Google Business Profile. Set it up for credibility; it rarely brings plant work by itself.
7. Marketplaces and paid ads. Last. The work is on site, and buyers on Upwork want remote writing at low rates.
After each pilot, ask the quality manager for two numbers you can share without the company name: time to train a new operator on that task before and after, and scrap or rework on that task. Ask for a reference call and an introduction to one supplier or customer plant. Show a redacted page of a finished instruction, never a client’s drawing. More in the launch and marketing playbook.
Running it week to week
Schedule filming during day shift when the best operators are on and the line can spare them for an hour. Draft the same week while it is fresh. Keep a log for each client of every document, its version, who tested it and who signed it. Follow up on unsigned drafts weekly; a draft that waits a month is a draft that dies. Once a quarter, ask each client what changed on the floor so instructions get revised, not forgotten.
Rules to check
No license is needed to write work instructions, and you should never claim one you do not have. Under ISO 9001 the plant controls its documented information and the certification body audits it; do not promise certification or a passed audit. OSHA’s lockout/tagout standard makes the employer responsible for energy-control procedures, their annual inspection and certification; the plant’s safety lead verifies and signs, not you. Other OSHA rules, such as machine guarding and hazard communication for chemicals, may apply to the tasks you document, so put safety steps in front of the plant’s safety lead every time. Respect confidentiality agreements and export controls on customer drawings. Get written permission before filming any worker, and keep footage only as long as the contract allows.
What goes wrong
AI adds a torque value or temperature that nobody said; check every number against the video and the drawing. The veteran operator does it differently each time; film twice and ask why. The quality manager never signs; agree on a sign-off date in the pilot quote. A safety step is missing because it was obvious to the operator; the safety lead’s review exists to catch it. Translations go out unchecked and a step is wrong in Spanish; a fluent floor review is part of the price. And the plant puts your documents in a shared folder with no version control; offer a simple numbering and revision scheme as part of the job.
Questions people ask
How much does it cost to have SOPs written for a manufacturing plant?
As an estimate, about $150 to $500 per work instruction, or $3,000 to $10,000 for a set or a quality manual project. Complex or safety-heavy tasks cost more.
What is the difference between an SOP and a work instruction?
An SOP usually describes a whole process and who is responsible. A work instruction shows one task step by step at the machine, often with photos. Small plants often use the terms loosely; use the client’s names for things.
Can AI write ISO 9001 documents?
AI can draft them quickly from video, transcripts and notes. ISO 9001 requires the plant to review, approve and control its documents, so a person checks every step and the plant signs off. A certification body audits the result.
Who has to sign off on a lockout/tagout procedure?
Under OSHA’s 29 CFR 1910.147 the employer is responsible for the written procedure, a periodic inspection at least once a year by an authorized employee, and written certification of that inspection. A writer can format it, but the plant’s safety lead must verify it on the machine.
Can a college student do this part time?
Yes, if your schedule allows daytime plant visits; engineering and industrial technology students do this well, sometimes through a co-op. International students on F-1 visas generally cannot freelance for outside clients without work authorization, so ask your international student office first. More in For students.
